. To all to 7mm it may concern: f

Be it known that we, FREDERICK G. REID, a citizen ofthe Dominion ofCanada', and HALT R B. ALLI'soN, citizen of theUnit'ed State's. both residing at Buffalo, county of Erie, State of New York, have invented certain new and useful Improvements in Disk- Whee'l Construction; and we do declare the following to be a full, clear, and exact description of the same, reference being bad to the, accompanying drawings, and to the characters of reference marked thereon,

which form apart of this application.

A This invention relates to improvements 1n vehicle wheels employing solid metal disks instead of spokes, and being also adapted to carry demountablerims for pneumatic tires.

The principal object of our inventionls to provide a method of securing the dlsks to the fixed rim of the wheel so that the rim and disks will be positivelysupported and held relative to each other, a locking ring for the demountable rim being also provided and designed to co-operate with the fixed rim and disks in such a manner that a clamping'of the latter in place is had, so

that a very substantial and rigidly connected structure is thereby obtained, from which all possibility of relative radial movement is eliminated. I f

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly efl'ective for the purposes for which it is designed.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of ref.

erence indicate corresponding parts in the several views. 7

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes the fixed rim in general, being preferably a channel shaped member with the opening facing outwardly. One side 1 of the rim is formed with a transversely disposed groove 2 adjacent its outer periphery and facing toward the opposite side 1 of the rim. Saidopposite side is of lesser diameter than the grooved side and is FREDERICK G.'"REID AN D VIALTE R B.'.ALL ISON, OF BUFFALO, NEW YOBK, t-SSIGNORS TO HARVEY JV HEEL 'CQ-MBANY, ING, OE BUFFALQJVEW YORK.

While this specification sets forth in detailthe present and preferred construction of the device, still in practice such. deviations from such detail may be resorted to as do not form a departure from'the spirit of the invention, as defined by the appended claims.

Having thus described our invention, what we claim as new and useful and desire to secure by Letters Patent, is

1. In disk wheel construction, a fixed rim the outer face and one side of said rim having a beveled portion formed therewith, and

a disk extending to and lying against the said side of the rim and being bent to also portion of the rim and being fixed thereto,

a locking ring for a demountable rim provided with a beveled face adapted to bear on the bent portion of the disk and with a straight portion adapted to bear against that portion of the disk which lies against the side of the fixed rim.

3. In disk wheel construction, a fixed rim the outer face and one side of said rim having a beveled portion formed therewith, a disk lying against the said side of the rim and being bent to also lie against the beveled portion of the rim and being fixed thereto, a locking ring for a demountable rim provided with a beveled face adapted to bear on the bent portion of the disk and with a straight portion adapted to bear against that portion of the disk which lies against the side of the fixed rim, and means for holding and clamping said locking rim in position and against the disk surfaces and demountable rim.

4L. In a disk wheel construction, a fixed rim having a beveled portion formed on one side thereof adjacent the outer face, a disk extending to and lying against said side and beveled portion of the rim, and an endless locking ring for ademountable rim having an endless wedge shaped portion adapted to pass between the demountable rim and the bent face of the disk and to bear thereagainst throughout its extent.

In testimony whereof We affix our signatures.
